MILK PIPE UNION GASKETS DIN 11851
The milk pipe fitting was originally developed for connecting the milk hose to the milk pipe.
In the meantime, however, dairy pipe union seals are used throughout the food industry as well as in the chemical and pharmaceutical industries.
In the sealing sector, NBR, EPDM, silicone, FPM and PTFE as well as an O-ring FPM coated with PTFE have established themselves as standard.
